Sorry, not sure I understand. Do you mean that DHTs have strong 
connectivity requirements (e.g. nodes should be able to communicate with 
their direct successors on the ring etc)? In that case, there are DHTs 
which relax these requirements, e.g. small-world DHTs (Oscar, Symphony) 
and those that don't have a ring or lattice (P-grid, FuzzyNets, Kelips). 
Or do you mean that DHTs do not route efficiently because they ignore 
latencies (what's called stretch, or proximity awareness, or locality by 
the DHT folks). Or perhaps neither :).
